Etude préliminaire visant la détermination de seuils de confort pour un zoom haptique BIBAFull-Text 3-10
  Mounia Ziat; Olivier Gapenne
In order to resolve PDA display problems, we validated, in a previous study, the efficiency of a new zooming technique associated with a tactile feedback (haptic zoom). The displayed objects on a PDA screen being relatively small, it appears essential, in the present study, to define minimal and maximal comfort thresholds to ease gesture execution that correspond to zoom-in and zoom-out thresholds of the haptic zoom. The results of the experiment undertaken with a sensory substitution device show that: i) the choice of an object size close to 4 cm significantly increases the recognition rate, ii) minimal and maximal comfort thresholds, defined by a ratio C (see text), seem to be respectively at values of C=0.2 and 0.4, iii) strategies used by subjects prove to be productive if they agree with the requested task (estimate figure size and orientation) and the explored shape topography.
Saisie de données pour interfaces réduites avec Glyph: principes, niveaux de saisie et évaluations théoriques BIBAFull-Text 11-18
  Gurvan Uguen; Franck Poirier
Glyph is a new data entry method designed for different interaction styles. Glyph is based on a reduced set of six shape primitives, plus a seventh "segmentation primitive". The data input is made by seizing sequences of primitives with a maximum length of three.
   The segmentation primitive allows to handle three input modes: character input, text edition and system command. The character input is based on a decomposition in basic shapes according to a principle of analogy with Roman characters.
   This paper presents the different input levels, the character charts, and results of a theoretical evaluation on the character input. Two types of interface are considered. The first one is a dynamic soft keyboard specifically designed for stylus-based entry and the second one is a reduced physical keyboard design for devices as phone portables.
VirHKey: un clavier gestuel hyperbolique avec retour visuel BIBAFull-Text 19-26
  Benoît Martin
The VirHKey uses a new Unistroke text entry method. Gesture recognition is accomplished through a sequence of flicks. This recognition is deterministic, enabling good accuracy. It is done continuously to provide a focus and context visual feedback by using the hyperbolic geometry. This is helpful at the learning stage: the user is able to learn swiftly the gestures to make to reach the right character. We expect that the visual feedback will be helpful for beginner users and should become unnecessary for expert users after few hours of use. Usability tests show very good results compared to existing propositions.
Exploration d'analyse de données textuelles et navigation contrôlée dans OCEAN BIBAFull-Text 27-34
  Christian Jacquemin; Helka Folch; Sylvaine Nugier
In order to acquire the concepts related to a professional domain, 4600 web pages are structured into 900 hierarchical clusters by TEMIS. The design of the 3D interface for exploring these classes is described together with a qualitative evaluation by six professionals.
   The interface is defined through an XML language for virtual world design. Scene graph and behavior is automatically generated from textual data analysis and provides users with a multi-scale controlled browsing of the hierarchical structure. The evaluation shows that users are satisfied with the interface even though some discontinuities in interaction should be avoided.
Influence de l'organisation spatiale des affichages sur l'efficacité de la recherche visuelle BIBAFull-Text 35-42
  Jérôme Simonin; Suzanne Kieffer; Noëlle Carbonell
The aim of this experimental study was to investigate the possible influence of spatial layout on the efficiency and visual comfort of target detection on crowded displays. Four layouts were used for presenting sets of 30 realistic colour photos: Random, Elliptic, Radial and Matrix-like. 120 scenes (30 per structure) were displayed to 10 subjects. For each scene, subjects had to detect a previewed photo, and to select it using the mouse. As expected, target selection times and failure numbers were influenced by task difficulty, target position and photo subject. Eye-tracking data suggest that, during the initial survey in search of the target, Elliptic layouts provided better visual comfort than any of the other layouts (shortest scan paths), and proved to be sensibly more efficient than Matrix layouts (shorter initial survey durations). All these results are significant.
Mat'Graph: transformation matricielle de graphe pour visualiser des échanges électroniques BIBAFull-Text 43-49
  Benoît Otjacques; Fernand Feltz; Gilles Halin; Jean-Claude Bignon
Graph and matrices are two well-known solutions for representing network data. Each of them presents some advantages and drawbacks. The approach discussed in this paper consists in transforming a graph on the basis of a matrix-based organisation of the visualization space, in order to obtain a new trade-off between the two kinds of representation. This technique, called Mat'Graph, has been used to visualize the e-mail interactions between the members of a construction project.
Asymétrie du transfert modal lors d'un dialogue personne-machine BIBAFull-Text 51-57
  Ludovic Le Bigot; Valérie Botherel; Éric Jamet; Jean-François Rouet
The aim of this study was to explore modal transfer effect with the use of retrieval information system. Forty-eight participants took part in a series of twelve tasks with a dialogue system presented either in the written or the spoken mode during the first six dialogues. The next six dialogues were then presented either in the same interaction mode or in another mode. The analysis of the results showed a changing of interaction mode reduced efficiency. Moreover, beginning by oral mode had a positive effect on the next interactions with both oral and written modes. The implications of the results are briefly discussed depending modality effects on natural language dialogue interaction.
WWHT: un modèle conceptuel pour la présentation multimodale d'information BIBAFull-Text 59-66
  Cyril Rousseau; Yacine Bellik; Frédéric Vernier
Multimodal presentation of information aims at using several modalities of communication to produce relevant outputs to the user. This presentation involves different concepts regarding to information, interaction components (modes, modalities, media) and interaction context. An incremental process is required to create an adapted presentation. This paper presents a conceptual model for the multimodal presentation of information called WWHT and based on four concepts: What, Which, How, Then. These concepts describe the life cycle of a multimodal presentation from its birth to its disappearance including its evolutions. The application of the model is introduced through the outputs specification of a mobile phone application.
VOICE: une plate-forme vocale pour la formation au contrôle aérien BIBAFull-Text 67-74
  Philippe Truillet; Gwenael Bothorel
In the early 1990's, developers relied on hardware to make speech recognition a reality. Features desired by air-traffic controllers, such as the ability to use dynamic call-signs and compound messages, became more feasible with the advances of the technology. Hence, the introduction of Automatic Speech Recognition (ASR) in ATC simulators can solve some problems correlated to pseudo-pilots.
   This paper examines first the challenges and opportunities of developing voice recognition solutions in ATC simulators using complex grammars. A first experiment concerning call-sign recognition is discussed relatively to grammars.
   Then, the VOICE project is presented which develops a generic approach that recognizes simple clearances and callsigns.
De la modélisation des dysfonctionnements d'un système complexe à la déduction des besoins informationnels des utilisateurs: une transition difficile en IHM BIBAFull-Text 75-82
  Faouzi Moussa; Christophe Kolski; Meriem Riahi
In industrial processes, the dysfunction modelling step is a must. It is performed in the beginning of the design process. Information carried out in this step offers a great opportunity to deduce the users informational needs. However, going from the dysfunction modelling step to the user's informational needs deduction step still seems to be difficult and is often miss studied on complex cases. In this paper, we present a way of solution. An illustration is given too.
Proposition d'un noyau et d'une structure pour les modèles de tâches orientés utilisateurs BIBAFull-Text 83-90
  Vincent Lucquiaud
User task analysis is a critical step in the design process of interactive systems. The large set of user task models available today may lead to assume that this step is well supported. These models, which possess sometimes an associated tool, expose a wide spectrum of proficiency such as evaluation, interrogation, or simulation. Temptation to use them jointly presume interworkings. But, even at the syntactic level it remains impossible. Furthermore, following various work, problems appear as well on task's characteristic, as documentation or coherency. To try to remedy, a modular approach is proposed to structure these models and answer these requirements. Thus, we will expose here our central module, the core, which contains minimal data to describe the activity and this, independently of any idea of specialization.
Modélisation orientée tâche de la navigation d'une application web: catalogue des thèses de I'AFIHM BIBAFull-Text 91-98
  Marco Winckler; Christelle Farenc; Eric Barboni; Florence Pontico
Web applications are a part of our daily lives as a source of information. They support e-learning, the organisation of internal company practices, e-commerce and so on. A number of such Web applications implement electronic procedures where users with several responsibilities participate. Such electronic procedures can be described as a collaborative activity where individual user tasks play an important role in the whole process. The goal of this paper is to show that the design of Web applications supporting electronic collaborative procedures requires both modelling of individual user tasks as well as the description of the interconnection and interaction between tasks. We illustrate our approach using a case study for the Association Francophone d'Interaction Homme-Machine (AFIHM) thesis catalogue. This case study describes several design phases from requirements engineering to implementation highlighting the role of navigation models as a means to describe collaborative user interaction over Web applications.
Gestion de l'inter-activités pour le support au développement logiciel coopératif BIBAFull-Text 99-106
  Arnaud Lewandowski; Grégory Bourguin
Software development is a cooperative activity, since it implies many actors. We focus on CSCW integrated global environments. Our study of existing platforms supporting software development activities points out their lacks in terms of tailorability and cooperative support. Upon previous results we obtained in the CSCW domain, we propose to extend the Eclipse platform, in order to offer a new support for software development by creating a cooperative context for the activities supported in Eclipse by each integrated plug-in.
Premières évaluations d'un bureau virtuel pour un processus de conception augmenté BIBAFull-Text 107-114
  Stéphane Safin; Christelle Boulanger; Pierre Leclercq
Many CAD tools already allow to create and manipulate directly ideas in a digital way. However, designers still use the pen and paper technique during the early design phase of their projects. Indeed, existing CAD tools constraint the creative work. There is a need for a spontaneous human computer interaction in design computing. In order to answer to this need, we develop an integrated aided design tool based on an Virtual Desktop. The designer sits in front of a classical desktop where s/he can create and manipulate drawings and generated models. The paper relates the observations made from an experiment about the use of the Virtual Desktop by a designer. That experiment demonstrates that the immersive aspect of our system interface modifies the relation existing between the designer and his/her model and, this way, its generates a new type of augmented interaction.
Enquête sur les pratiques de tests d'utilisabilité BIBAFull-Text 115-122
  Naouel Moha; Li Qing; Ashraf Gaffar; Ahmed Seffah
This paper reports the results of a recent survey on usability testing involving nearly a hundred usability practitioners. The purpose of this survey was to identify the practices in usability testing. The analysis of those results allows to present a state of art in this domain and to identify the strengths and the weaknesses. As weakness, we have noted the lack of specific tools for collecting and analyzing test data; as strength, the promotion of this expert domain inside companies.
Principes et architecture pour la personnalisation d'information en interaction homme-machine, application à l'information transport BIBAFull-Text 123-130
  Abdouroihamane Anli; Christophe Kolski; Mourad Abed
The personalization of information consists to provide to a user relevant information corresponding to its preferences and its needs. This domain being in constant evolution, the systems delivering personalized information cannot be fixed. We propose PerSyst, a framework based on software agents, being able to be used as support for the design of a Personalization System. PerSyst facilitates the management and the transmission of personalized information in a distributed and a evolutionary system. PerSyst is applied for the personalization of transport information. It is for helping users in their choice of routes, for informing them of the disturbances and for guiding them all along their trip.
Une utilisation du modèle MVC pour une plate-forme de travail virtuel BIBAFull-Text 131-138
  Nicolas Martin; Samuel Degrande; Christophe Chaillou
Nowadays, 3D interfaces appear more and more in the users' environments. The arrival of the third dimension adds certain contributions to the interfaces but the existing systems only integrate 2d applications in a virtual environment without proposing real innovation in term of chi 3d. In this article, we carry out a feedback on the use of the MVC paradigm for the architecture of a 3d desktop: Spin|3D.
INDIGO: une architecture pour la conception d'applications graphiques interactives distribuées BIBAFull-Text 139-146
  Renaud Blanch; Michel Beaudouin-Lafon; Stéphane Conversy; Yannick Jestin; Thomas Baudel; Yun Peng Zhao
The INDIGO project develops a new generation of tools for distributed interactive applications. The proposed architecture is composed of object servers that manage the applications's data and interaction and rendering servers that manage display and interaction. Such separation of the core application logic from the interaction makes it possible to optimize graphical rendering and interaction according to the current setup and context. This approach was validated through examples that illustrate various types of presentation and interaction devices.
Validation d'une approche « basée sur exemples » pour l'apprentissage de la programmation BIBAFull-Text 147-154
  Nicolas Guibert; Laurent Guittet; Patrick Girard
Although computers and programs have now become essential in experimental sciences as analysis or measurement tools, many students still find learning Computer Science is extremely difficult. Many studies have characterized the errors and difficulties encountered by novice programmers. From some years, we explore the use of a particular paradigm, programming by examples, to lower these difficulties.
   The work being presented here intends to be a first evaluation of this approach, in connection with the difficulties reported by the authors. Two experiments of MELBA, the tool developed in the context of the project, are thus described and discussed.
Aide a l'utilisateur: savoir quand intervenir BIBAFull-Text 155-162
  Mick Philippon; Alain Mille; Guy Caplat
This paper is about spontaneous user assistance. In this case, the help system not only has to provide accurate help, but it must also provide it on time, and without any precise request made by the user. We propose here to use the 'traced experience based reasoning' to provide the user accurate help, and to establish a dialog a posteriori between the user and the system in order to teach the system when it must intervene.
Environnements virtuels pour l'apprentissage: de l'image d'epinal à la réalité des usages et des configurations socio-techniques BIBAFull-Text 163-170
  Jean-marie Burkhardt; Domitile Lourdeaux; Flore Lequatre
This paper describes a survey on the use and the sociotechnical configurations of Virtual Environment for Training and Education (VET/E). The characteristics of 17 VET/E were collected based on a questionnaire, interviews and data in the literature. The questionnaire was sent between may and july 2004. Descriptive statistics of the data enable us to suggest four main patterns of current design of VET/E thanks to the pedagogical and use configuration. Each pattern favours specific alternatives in terms of the interaction devices, users' representation, users' feedback and offered guidance. The limits and perspectives of this work are finally discussed.
Collaborer pour mieux apprendre d'une animation BIBAFull-Text 171-176
  Cyril Rebetez; Mireille Bétrancourt; Mirweis Sangin; Pierre Dillenbourg
Studying multimedia animations for learning leads to question their ability to enhance comprehension of complex materials in comparison with static graphics. An often raised difficulty is their changing nature and the burden of higher amounts of information to process at the same time. We suggest using a permanent summary of visual information through snapshots, accessible on the screen. We also studied the impact of static or dynamic presentations, and collaborative (peers) or individual learning conditions. The results of this experimental study show benefits of dynamic presentations for memorization. Deep learning is also better in animated condition but only for peers. Last, snapshots are helping individual learners but not the peers. We discuss and explain these results on the basis of guidelines and a splitinteraction hypothesis.
Typographie et sélection de sites internet BIBAFull-Text 177-183
  Jérôme Dinet
This paper investigates the impact of typographical cues on Websites selection. 174 participants (Grade 5, 7, 9, and 12) were asked to select relevant Websites for six different search tasks. In each list of Websites, some of them were relevant while other were irrelevant, with or without typographical cues on the keywords extracted of the search topic. Results obtained have mainly shown that the presence of these typographical cues influenced the strategies of selection for younger pupils who used essentially a simple lexical matching.
La perception du mouvement dans les systèmes de visualisation d'informations BIBAFull-Text 185-192
  Agnès Saulnier
The semiology of graphics introduced by Bertin is a complete system composed of signs and rules in order to build planar maps or diagrams. This system is powerful to represent, memorize, understand and communicate information. In this paper, we study experiments in motion perception to propose an extension of this system with one additional dimension, the movement. The combination of this new variable with existing static ones will be studied according to the properties of visual perception.
Démarche d'évaluation de l'usage et des répercussions psychosociales d'un environnement STIC sur une population de personnes âgées en résidence médicalisée BIBAFull-Text 195-198
  Christine Michel; Marc-Eric Bobillier-Chaumon; Véronique Cohen Montandreau; Franck Tarpin-Bernard
The MNESIS Project aims to see whether the use of computerized environment by elderly people in medicalized residences stimulates their cognitive capacities and contributes to a better integration, recognition or acceptance within their social environment (friends, family, medical staff). In this paper we present the protocol of evaluation that is defined to check this assumption. This protocol is between users' centred traditional protocols (built on investigations and indirect observation) and studies of Web Usage Mining (where knowledge databases about the uses are built from traces of use). It allows collecting direct and indirect information on a large scale and over long periods.
Construction d'une base de connaissance pour l'évaluation de l'usage d'un environnement STIC BIBAFull-Text 199-202
  Christine Michel; Yannick Prié; Loïg Le Graët
Our goal is to determine how people will adapt to a computerized environment while they are a priori not educated to their manipulation. We chose to couple two methods: regular observation using the traces of use generated by the interactions of the user with the system and more specific investigations. The combination of these two types of data in such context of study is original. In this paper we present the means used to collect, characterize and organize the observation data so that it is possible to exploit for various types of analysis.
Intégration de l'analyse des besoins des utilisateurs pour la conception de systèmes d'information voyageurs BIBAFull-Text 203-206
  Assia Mouloudi; Pierre Morizet-Mahoudeaux; Annette Valentin; Claude Lemarchand
This paper concerns the problem of designing an information system for public transportation users. The aim of this system is to centralise data issued from different sources and to select those, which are relevant for built useful information for the users. In this work we propose an approach to link data representing the actual users' needs with data available in the transportation network management system. The steps to find the links between users data and information sources have been, firstly to identify the actual users needs, secondly to characterize and assess data available in the information network management system, and thirdly, to select those, which are relevant to provide the users with efficient.
Etude empirique de l'utilisation de la géolocalisation en collaboration mobile BIBAFull-Text 207-210
  Nicolas Nova; Fabien Girardin; Pierre Dillenbourg
This paper describes a collaborative location based application in built-in environment. This system is basically a platform that aims at exploring the impacts of positioning technologies on collaborative processes involving geographically dispersed teammates. The paper presents the platform as well as the first results of an ongoing study in which we tested two interfaces: one with a location awareness tool and another without. Results show that being given the position of the partners does not lead to better performance. Moreover, participants who were not provided with the position of others sent more messages to each other's and made more mistakes when we asked them to draw the path taken by their partners.
Architecture dirigée par les modèles pour une représentation multi-vues du contexte de coopération BIBAFull-Text 211-214
  Gilles Halin; Sylvain Kubicki
Nowadays, new tools appear to assist the cooperative activities of design and realisation. These tools have to integrate the context to better answer to the users' needs. Taking into account the context allows to define relevant information and functionalities for the user, or to suggest adapted interfaces for specific needs. This article describes a model driven architecture (MDA) allowing the integration of different visualisation modes by selecting information in the cooperative context.
Interaction adaptative pour systèmes coopératifs: raisonner sur les discordances BIBAFull-Text 215-218
  Michel Munoz; Pascale Zaraté; Jean-Luc Soubie
Task execution support systems have to adapt to any problem occurring during activity in order to provide help as cooperatively as possible. The need for adaptativity is also present in the interactions between the system and users. In this paper we present first elements of a framework contributing to the adaptative capability of systems. The core of this framework is reasoning about and solving conflicting elements of the current situation. This approach can be used seamlessly at any level of adaptation (i.e. cooperation, activity, dialog, interaction...).
Ordinateur porté: dispositifs d'entrée sortie BIBAFull-Text 219-222
  Diane Lingrand; Wagner Ourique de Morais; Jean Yves Tigli
Among the different challenges induced by Wearable Computing, is the one of IO devices. The choice of appropriate input device is driven by the user context and the availability of motor resources of the user.
   The substitution of one device by another with same functionalities is not sufficient.
   After the introduction of input devices classification, we show that it is necessary to introduce a user model for input devices considerations. A simple example based on motor resources of the user permit to illustrate our method.
Affichage d'informations par des impulsions haptiques BIBAFull-Text 223-226
  Thomas Pietrzak; Benoît Martin; Isabelle Pecci
Our goal was to find haptic effects that could be used to present information to the user of a haptic pointing device. We present a study on users' ability to discriminate between different effects presented with a PHANToM haptic pointing device. The effects we experimented with were bumps that the user could feel through the PHANToM. The direction and the amplitude of the bumps were manipulated. The results show that the direction is easy to discriminate, but the amplitude is not. Only two levels of amplitude could be reliably discriminated.
TACTIBALL,TACTIPEN,TACTITAB Ou comment « toucher du doigt » les données de son ordinateur BIBAFull-Text 227-230
  Eric Lecolinet; Gérard Mouret
This paper is dedicated to the augmentation of standard pointing devices to provide a simple symbolical form of tactile feedback. Several prototypes and applications have been developed to show the feasibility of the approach. The final goal of the study is to evaluate how simple tactile devices can be used by non blind people in conjunction with vision.
Effets du retour de force sur la performance lors d'un geste de pointage BIBAFull-Text 231-234
  Bertrand Tornil; Nadine Baptiste-Jessel
This article present a survey about a point-and-click task. This task was done with a force feedback mouse. Compared with a point-and-click task without force feedback, we have not observed a significant reduction of the performance when the target got a force feedback. However, when some other force fields are between the target and the movement origin, (haptic desktop for instance), performances decrease about 23,6%. We propose a dynamic force feedback, where the force intensity decreases when the mouse speed raises up. Performances are again worse than without force feedback, but only about 15,6%.
Conception et évaluation expérimentale d'interfaces de saisie stylo pour systèmes mobiles de petites tailles BIBAFull-Text 235-238
  François Bouteruche; Eric Anquetil; Guillaume Deconde; Eric Jamet
This paper presents a study on the handwriting input interfaces for small-size mobile devices. The design of these interfaces has been associated to an experimental evaluation of their qualities from a cognitive psychology point of view. First, we resume the principles of our input interfaces based on our handwritten character recognition system. Then, we describe two experiments that have been conduced and their conclusions. The first concerns the design of an educational software build to allow a fast and efficient start with the interface. The second evaluate the interface quality and focuses on the hypotheses that underlie our design principles.
Pour une meilleure utilisabilité des pages web par des handicapés moteurs: modèle de Fitts et méthodes de conception centrée-utilisateur BIBAFull-Text 239-242
  Frédéric Vella; Agnès Collignon; Amélie David; Valérie Chabbert; Nadine Vigouroux
The objective of this paper is to show that a step of user-centred design makes it possible to increase and to facilitate/optimize the interactivity of Internet. Some standards of accessibility exist but they answer only partially to the constraints of the handicapped people (motor constraints and tiredness). In this article, we propose to describe the step adopted for the specification of an interaction interface that aims to reduce the distance to be traversed, in the meaning of Fitts' models, and thus to reduce the tiredness of the handicapped people.
Convergence possible des processus du data mining et de conception-évaluation d'IHM: adaptation du modèle en U BIBAFull-Text 243-246
  Mohammed Ali Lajnef; Mounir Ben Ayed; Christophe Kolski
In this article, we propose an approach aiming to integrate stages of a data mining process into a development model; this so-called U-model is enriched under the human-computer interaction point of view. We also try to show its use in a framework concerning decision support system design. Our objective is to find methodological similarities between human-computer interaction and data mining domains.
Vers l'utilisation de la mémoire épisodique pour la gestion de données familières BIBAFull-Text 247-250
  Nicolas Roussel; Jean-Daniel Fekete; Matthieu Langet
The quantity and diversity of digital information we produce, receive and download on a daily basis is now incompatible with the available tools for managing it. In this paper, we present a new approach to familiar data management that aims at taking advantage of the episodic memory of the user. We describe some of our ongoing work that aims at providing interactive systems with a long-term memory that would allow users to easily retrieve a particular data or context.
Coupe projective pour une tâche trajectorielle dynamique BIBAFull-Text 251-254
  Pierre Salom; Rémi Megret; Yannick Berthoumieu
Volume visualization using 2-D slices is a technique used in several scientific fields such as medicine, geology or any other industrial application using 3D data. The expert has the possibility to explore the data by displaying a set of slices extracted from the volume. The objective is to detect some specific three-dimensional structure and point it in 2-D, directly on slices with a device. This type of interaction realized during the animation of slices is named dynamic pointing. To formalize this task we define in this article a new paradigm: the dynamic steering task (DST). We first relate it with the other tasks studied in Human-Computer Interaction. This study helps us to better understand the reason of the difficulty of this task and why users produce so many positioning errors. We formulate the hypothesis that the errors generated in a DST are coming from the impossibility for the experts to anticipate the structural variations of the structures to be pointed. In order to solve this problem we propose a new technique of visualization, which facilitates anticipation, called the projective slice. The effectiveness of this tool and the veracity of our assertions are determined experimentally.
Gestion des fenêtres: enregistrement et visualisation de l'interaction BIBAFull-Text 255-258
  Olivier Chapuis
The recent graphical rendering models of desktop computers can be used to explore new window management techniques. In order to evaluate these new techniques, we should have tools that help us better understand how users manipulate their windows. We present a log and visualization tool of the Human-Window interaction for the X Window system. The tool allows to replay a session (without the windows contents) as a video. A filtering system allows to select and easily access high level actions. We give some examples of application of this system.
Visualisation multi-échelles pour photos personnelles BIBAFull-Text 259-262
  Emmanuel Nars
The number of pictures taken every year increases and it is more and more difficult to manage all the pictures we own. In this paper, we present a prototype to manage interactively ours pictures. This prototype allows creating and browsing subgroups of pictures. These subgroups have the property to contain pictures taken in a time interval defined by the user.
Une approche MDS hybride pour l'exploration visuelle interactive BIBAFull-Text 263-266
  Fabien Jourdan; Guy Melançon; Christophe Douy; Alexandre Gasne
The paper presents a novel technique for the exploration of an information space where elements are associated with a taxonomy and where each element has an associated attribute vector. A hybrid MDS method is at the core of the method. The underlying algorithm embeds elements in the 2D plane, trying to place "similar" elements close to one another. The dynamic character of the algorithm makes it a well suited tool for interactive exploration. Our first results presented here confirm our approach as a tool relevant for finding merging opportunities between companies based on various economic characteristics.
Librairie de widgets dialogiques pour un agent conversationnel assistant BIBAFull-Text 267-270
  David Leray; Jean Paul Sansonnet
This paper describes a library of Dialogical Widget for a mediator architecture. It provides a development framework for software designers willing to include a conversational assistant agent.
Génération d'émotion pour le robot MAPH: média actif pour le handicap BIBAFull-Text 271-274
  Mathieu Petit; Brigitte Le Pévédic; Dominique Duhaut
This paper presents our work in progress in the field of emotional synthesis for psychological and physiological enrichment applied to children with mental or physical diseases. We present a robot, MAPH, which should be able to entertain affective relationship with children by using speech and emotional synthesis capabilities. Then we present a way to create an emotional face. This face will combine emotional richness of facial expressions with a simple mechanical design. Testing and evaluating different faces will provide us a way to design the face that best fits to the robot MAPH.
Extraction des expressions faciales en présence de rotation hors plan BIBAFull-Text 275-278
  Julien Peyras
This article presents a new method for facial content analysis and face deformation extraction on video sequence. Rigid movements and inner deformation of the face are tracked with a classical AAM. The fit model is consequently projected onto a set of vectors representing the head rigid movement only; a new model private from inner deformation can then be created. The extraction of the image visual content on the very position of this model allows to create a new image sequence showing the righted inner face with its expressivity conserved. The method proposes an original solution to perform face expression extraction in presence of out-of-plane rotation. We will eventually introduce a new method of expression recognition used for testing the method.
Metisse: un système de fenêtrage hautement configurable et utilisable au quotidien BIBAFull-Text 279-282
  Nicolas Roussel; Olivier Chapuis
Twenty years after the general adoption of overlapping windows and the desktop metaphor, modern window systems differ mainly in minor details. While a number of innovative window management techniques have been proposed, few of them have been evaluated and fewer have made their way into real systems. In this paper, we present Metisse, a fully functional window system specifically created to facilitate the design, the implementation and the evaluation of innovative window management techniques.
Etude empirique de l'interaction multimodale en mobilité: approche méthodologique et premiers résultats BIBAFull-Text 283-286
  Guillaume Calvet; Pascal Salembier; Julien Kahn; Moustapha Zouinar
This paper sums up the first results of an empirical study on the use of a multimodal device in mobility in the context of a collaborative game. The main features of the data gathering and analysis platform is described, then some results on the use of multimodality are presented.
Virtualisation d'interfaces matérielles par l'intermédiaire d'un ordinateur porté BIBAFull-Text 287-290
  Alexandre Plouznikoff; Nicolas Plouznikoff; Jean-Marc Robert
After reminding the complementarity of wearable and pervasive computing, this paper describes the principles of hardware interfaces virtualization through wearable computers. We present the benefits of this approach and our current prototype's architecture. Our preliminary results show that, even though virtualizing hardware interfaces does not currently improve user performance, it can enhance user satisfaction.
Collecter les usages réels des clients de téléphonie mobile (un outil embarqué) BIBAFull-Text 293-298

This paper describes an application implemented on several mobile phones with open OS (Windows CE and Symbian 6 and 7 compatible). This application is a real tool used for experimentations, and which gathers frequency uses, duration and navigation (press on the keypad and history of windows opened). Without any constraint for users, this application makes it possible to identify functionalities used (directory, calendar, SMS' number received and sent...), duration and navigation (keys pressed...). In addition, this tool allows to carry out remote tests with real customers. An operation description and different results obtained are presented. Furthermore, the limits and advices are also described.
Quel impact de l'entrée vocale sur la conception graphique d'un service mobile? BIBAFull-Text 299-306
  Laurent Karsenty; Stéphane Sire; Mickael Causse; Nicolas Deherly
The development of multimodal interfaces exploiting voice input will appear in a number of cases as an evolution of an existing graphic design. Between minor adaptation and full re-design, the question arises as to which impact such an evolution could have on existing user interfaces. To bring initial answers an experiment was conducted within the European project Use-Me.Gov in which our goal was to redesign an existing service broadcasting news on municipal events by adding natural language voice input to it. This communication reports the main results of this experiment as well as the lessons that we drew from it.
La conjuration de l'erreur humaine: accepter ou refuser le risque, lequel? BIBAFull-Text 307-311
  Florence Reuzeau
What is it looking for when studying human error? Mastering the consequences of human error in the perspective of improving aviation safety? Eradicate human error from the flight deck or maintenance actions? Managing the human error or to tolerating the consequences? Risk management is a responsibility shared by each actor of aviation domain and the approaches are various in order to take into account the variability of the operational situations. The use of human error analysis only is pernicious. The global performance of human-machine system is a delicious alchimistry between a aircraft easy to operate, efficient, attractive, easy to understand, comfortable, suggesting cooperative team, with an acceptable workload in normal situations, abnormal and urgency situations.
Maturité, automation et expérience des utilisateurs BIBAFull-Text 313-320
  Guy Boy
This paper presents an approach to anticipate the maturity of a product taking into account user experience. Socio-technical systems evolve with the emergence of new practices. An analysis of this issue is presented in the context of highly-automated system development such as in aeronautics, and is extended to appliances of our everyday life. A product is truly accepted for routine use only when it is judged mature enough.

Environnement de conception et développement d'applications interactives selon l'architecture AMF BIBAFull-Text 329-330
  Guillaume Masserey; Chi Dung Tran; Kinan Samaan; Franck Tarpin-Bernard; Bertrand David
In this demonstration we are presenting a framework that supports the AMF (Multi-Facet Agent) approach which is a model-based approach. It allows building quickly interactive and adaptative software. AMF is a multi-agent approach, with a graphical formalism and an engine able to run AMF applications for which the control part is described in an XML file. After having introduced the research context, we are presenting the framework developed by the ICTT lab. This framework allows describing AMF applications through a specific editor showing alternatively a graphical view of AMF diagrams or a textural view of the XML control part of the application. Finally, this framework permits also to input the application code and to run the described applications.

It at the same time makes it possible to build personal spaces of information or in collaboration and to navigate there with an interactive and personalized dynamic interface.
L'Ecran noir: une vidéo pour sensibiliser les développeurs à l'accessibilité des sites web BIBAFull-Text 335-336
  Monique Noirhomme-Fraiture
In order to make aware students in computer sciences and more generally designers of Web sites, we have decided to realise a video showing the use of Internet by a blind person. Alain Thonet, a psychology student, is very adept at working with a computer. It is the means by which he carries out his work. In this video, he explains how he uses the computer with the aid of a vocal synthesiser and a Braille bar. In navigating three very common websites, he demonstrates the difficulties he encounters -- difficulties that could easily be avoided.

  Antonio Serpa; Bernard Oriola; Alban Hermet
VoCal is a vocal appointment manager running on Pocket PC founded by Microsoft Research in the framework of RFP embedded which is useful to evaluate usefulness and usability of standard PDA for visually impaired persons. The aim of this application is to allow blind users to manage their appointments on a Pocket PC during a mobility situation. This prototype has been developed using a centered design method 7. This paper deals particularly with VoCal functionalities and the non-visual interaction input/output modalities.
Conception d'une interface tangible pour l'assemblage en CAO BIBAFull-Text 339-342
  Ludovic Garreau
In this paper we present an operational tangible user interface dedicated to the mechanical CAD (Computer Aided Design) parts assembly. This platform is mainly based on the handling of physical objects. In our application field we show that our physical objects lead to take into account assembly constraints from the beginning of the design phase and especially during the phase of CAD model manipulation. We show how the use of our platform leads the designer to have a physical perception of the assembly constraints during the "virtual" phase of design on computer.
